Question

. Properties of the uniform, normal, and exponential distributions Suppose that x₁ is a uniformly distributed random variable, x₂ is a normally distributed random variable, and x₃ is an exponentially distributed random variable. For each of the following statements, indicate whether it applies to x₁, x₂, and/or x₃. Check all that apply. x₁ x₂ x₃ (uniform) (normal) (exponential) The probability that x equals its expected value is 0. The probability distribution of x has two parameters. The mean and standard deviation of x are equal.
